1.2 BCM57608 Ethernet Controller
The Ethernet controller is configured as a dual-port 200 Gb/s interface to the line side and x16 PCI Express v5.0 interface to the system host.
1.3 PCI Express Interface
PCIe is a serial interface standard for connecting high-speed components. The BCM57608 complies with the PCI Express Base Specification Revision 5.0, and supports a 16-lane PCIe 5.0 interface.
1.4 NC-SI Interface
The Ethernet controller supports the Network Controller Sideband Interface (NC-SI) Specification version 1.1.0. The NC-SI provides a standardized interface between the system baseboard management controller (BMC) and the integrated NC-SI module of the BCM57608.
1.5 SMBus Interface
The Ethernet Controller SMB0 interface supports serial communications between BCM57608 and the system. The interface allows the Ethernet controller to act as a SMBus primary or secondary device.
1.6 NOR Flash
The Ethernet controller requires a SPI NOR Flash memory to store the device firmware, PCI configuration space settings (for example, device ID, vendor ID), MAC address, and so on. After power-up, the firmware is downloaded into the device memory and executed by the on-chip processor.
1.7 Heat Sink
The passive heat sink is attached to the Ethernet controller using four spring-loaded push pins that are inserted into four mounting holes.
1.8 Power Supplies
All power is derived from the network adapter card host interface connector 12V and 3.3V supply which feeds the onboard regulators that provide the necessary power to the various components on the card.
1.9 Network Connectors
The controller integrates two QSFP 112 connectors to support 50/100G PAM-4 or 25G NRZ signaling enabling up to 200 Gb/s per port.

2 Board Power and Environmental Specifications
The BCM957608-N2200GQP00 thermal solution is optimized for GPU scale out in Artificial Intelligence (AI) clusters. In each node, one or more BCM957608-N2200GQP00’s are placed in front of the GPUs receiving airflow at 25°C to 35°C ambient. Table 3 and Table 4 provide the adapter power consumption and airflow requirements for typical AI cluster use models. The adapter is capable of supporting up to a 12W optic per connector. Using higher power optics than used in data collected for Table 3 and Table 4 will require additional airflow and slot power considerations. Evaluate these requirements and adjust system parameters accordingly. For uses in other system architectures, please contact your Broadcom sales representative for additional information.
